Specific embodiment
The present invention will be described more fully hereinafter with reference to the accompanying drawings now, shown in the drawings of certain implementations of the invention
Example.However, the invention can be reflected in many different forms and should not be construed as being limited to reality illustrated herein
Apply example；On the contrary, thesing embodiments are provided so that the disclosure will be thorough and complete by example, and will be to art technology
Personnel convey the scope of the present invention.Through this specification, similar appended drawing reference refers to similar element.
Fig. 1 is the schematic diagram for showing the mobile communications network 5 that can apply the embodiment herein proposed.Mobile communications network
5 include core network 3 and one or more network nodes 1, and herein, network node 1 has radio base station or evolution NodeB
1 form is also known as eNode B or eNB.Network node 1 can also have NodeB, BTS (base station transceiver) and/or
The form of BSS (base station sub-system).Network node 1 provides radio connection to multiple mobile communication terminal 2a-2b.Term is mobile
Communication terminal is also known as user equipment, mobile terminal, user terminal, user agent etc..
Mobile communications network 5 can for example defer to LTE (long term evolution), W-CDMA (wideband code division multiple access), EDGE (GSM
The enhanced data rates of (global system for mobile communications) evolution), GPRS (General Packet Radio Service), CDMA2000 (code point
Multiple access 2000) etc. any one or combination, as long as principle as described below is applicable.
Communication between each of mobile communication terminal 2a-2b and radio base station 1 passes through wireless radio interface
Occur.Network node 1 is also connected to core network 3 for being connected to central functionality and other networks.
Fig. 2A-Fig. 2 B is two differences shown for radio frame configurations used in the mobile communications network in Fig. 1
Exemplary schematic diagram.In the configuration shown in fig. 2, the first radio frame 10 includes ten subframe 11a-11j.Certainly, such as son
Indicated by arrow in frame, six subframes 11a-11b, 11e-11g, 11j are configured to downlink subframe and four sons
Frame 11c-11d, 11h-11i are configured to uplink subframe.Next (second) radio frame 10' and its ten subframes
11'a-11'j is configured in the same fashion.Identical configuration is continued until it for example due to the variation of load or wireless
The variation of electric condition and changed by network.
Mixed automatic repeat request (HARQ) includes the negative feedback when decoding unsuccessful from receiver to transmitter
(NACK) use of the affirmative feedback (ACK) and when successfully decoded from receiver to transmitter.
In the exemplary configuration of Fig. 2A-Fig. 2 B, shown with from downlink subframe to the arrow of uplink subframe
HARQ feedback (ACK/NACK).Therefore, each downlink transmission leads to the HARQ feedback in uplink subframe later.
Inverse process of the HARQ feedback for uplink transmission has been not shown herein.
Herein, the HARQ feedback transmitted in the uplink subframe of the second radio frame 10' is only shown, and is directed to future
Radio frame in an identical manner repeat feed back.
In fig. 2, the HARQ feedback for the 6th and the 7th subframe 11f-11g of the first radio frame 10 is in the second nothing
It is sent in the third subframe 11'c of line electricity frame 10'.On the terms bundled factor (bundling factor) is used to refer to and is single
The number of the associated downlink subframe of HARQ feedback in uplink subframe.Therefore, because according to two downlinks
The feedback of frame is incorporated in uplink subframe 11'c, and the binding factor for subframe 11'c is two.
For the 9th subframe 11j of the first radio frame 10, fourth subframe of the HARQ feedback in the second radio frame 10'
It is sent in 11'd.The therefore binding factor that the 4th subframe 11'd of second radio frame 10' has for one.
The HARQ feedback of the first and second subframe 11'a-11'b for the second radio frame 10' is in the second radio frame
It is sent in the 8th subframe 11'h of 10'.Since the feedback from the two downlink subframes is incorporated in the uplink
It in subframe 11'h, therefore is two for the binding factor of subframe 11'h.
For the 5th subframe 11'e of the second radio frame 10', nineth subframe of the HARQ feedback in the second radio frame 10'
It is sent in 11'i.The therefore binding factor that the 9th subframe 11'i of second radio frame 10' has for one.
Therefore, it can be seen that the binding factor can be easy to change between uplink subframe.
In the configuration shown in fig. 2b, the first radio frame includes eight subframes for being configured to downlink subframe
11a-11b, 11d-11g, 11i-11j and two subframes 11c, 11h for being configured to uplink subframe.About Fig. 2A's
Configuration, next (second) radio frame 10' and its ten subframe 11'a-11'j are configured according to same way.Once again, phase
Same configuration is continued until that it is for example changed due to the variation of load or the variation of radio condition by network.
The HARQ feedback of the 5th, the 6th, the 7th and the 9th subframe 11e-11g, 11i for the first radio frame 10 is
It is sent in the third subframe 11'c of two radio frame 10'.Therefore, the binding factor for subframe 11'c is four herein.
The tenth subframe 11j for the first radio frame 10 and first, second for the second radio frame 10' and
The HARQ feedback of four subframes 11'a-11'b, 11'd is sent in the 8th subframe 11'h of the second radio frame 10'.Therefore, needle
The binding factor to subframe 11'c is also four herein.
Fig. 3 is the schematic diagram for showing the resource allocation of the subframe of radio frame of Fig. 1.The some thin of LTE will now be described
It saves to set the context of the embodiment for herein proposing.It should, however, be mentioned that the embodiment herein proposed be not limited to
LTE is used together.
In the time domain, configuration is depended on, the subframe of 1ms duration is (when there are two of 0.5ms equal to each
Gap) it is divided into 12 or 14 OFDM (orthogonal frequency division multiplexing) or SC-FDMA (single-carrier frequency division multiple access) symbol.Depending on channel
Bandwidth and configuration, OFDM (or SC-FDMA) symbol include many subcarriers in frequency domain.One on one subcarrier
OFDM (or SC-FDMA) symbol is referred to as RE (resource unit).12 subcarriers on one time slot are referred to as physical resource
Block (PRB).
In LTE, no dedicated transmission channel is used for business.On the contrary, making in downlink and uplink the two
With shared transmission channel.These shared transmission channels, (uplink is shared by DL-SCH (downlink sharied signal channel) and UL-SCH
Channel), each scheduled device control, the scheduler assigns the different piece of downlink and uplink shared channel
To different UE (user equipment) to be respectively used to receive and emit.
The embodiment herein proposed is related to uplink.In the uplink, UL-SCH is mapped to physical uplink link
Shared channel (PUSCH) 20, for carrying user data.Control area 26 is located in frequency spectrum belt edge.In the control area 26
In, physical uplink control channel (PUCCH) is transmitted.PUCCH carries channel status related with down link data and refers to
Show (CSI), scheduling request (SR) message and mixed automatic repeat request (HARQ) feedback.
CSI and SR is always transmitted in the PUCCH resource being semi-statically configured.HARQ feedback report includes and previous receipt
The relevant ACK/NACK of down link data, transmitted in the dynamic area of PUCCH.
In the frequency spectrum for being assigned for PUCCH, code division multiplexing is used so that multiple PUCCH resources can share one
A Physical Resource Block (PRB).
CSI be also indicated as PUCCH format 2/2a/2b transmission (referred to here shortly as " format 2 ") and PUCCH most
It is transmitted on the exterior portion 23 of frequency spectrum belt edge.HARQ feedback report and SR are represented as PUCCH format 1/1a/1b
It (referred to here shortly as " format 1 ") and is transmitted in the inboard portion 24 for being closer to spectral band center of PUCCH.
Using various parameters, the position of scheduling request is configured into system bandwidth center always.Therefore, SR resource is placed in
It closer to band center is possible than HARQ feedback resource.
It should be pointed out that in all uplink subframes the initial position of different zones will be it is identical because time slot or
Number of subframes does not have dependence for initial position.
The full-size in HARQ feedback region will be used in the downlink subframe that the corresponding downlink of carrying is assigned
Control channel unit (CCE) maximum number it is proportional.Under normal circumstances, which allows different number of downlink
OFDM symbol is used for the downlink control area in different subframes.Therefore, have different number of CCE be it is possible, after
And it is possible for having various sizes of HARQ feedback region in different uplink subframes.
As explained above, with reference to Fig. 2A-Fig. 2 B, some TDD in TDD (time division duplex) configuration are configured, on
Line link HARQ feedback signal is also required to be bound to from two or more downlink subframes in a uplink subframe.This
Some TDD in a little TDD configurations, which are configured, to be carried also in different uplink subframes according to different number of downlink
The HARQ feedback of frame is expressed as the different binding factors.
It is repeated for such as scheduling request, HARQ, the different task of semi-persistent scheduling HARQ or HARQ channel selection etc,
UE can be assigned dedicated 1 resource of PUCCH format.
Scheduling request resources are requested UL-SCH resource by UE use.
HARQ, which repeats resource, can for example be assigned to the UE at cell edge to allow UE repeat ACK/NACK for several times
To improve the probability of acceptance.
It, can be by the semi-persistent scheduling of PDSCH resource block in order to save physical downlink control channel (PDCCH) resource
(SPS) it is assigned to UE.Then semi-static 1 resource of PUCCH format must also be established to transmit ACK/NACK on it for UE.
HARQ channel selection resource can be assigned to UE, need in a HARQ transmission (in LTE version 8 and version 9
In, most dibits are possible, but in version 10, by using channel selection, can send up to 4 bits) in pass
Send more than two ACK/NACK bits.
Fig. 4 A- Fig. 4 B is that the resource shown in two different scenes for the HARQ feedback in uplink subframe uses
Schematic diagram.Horizontal axis repre-sents are directed toward the index n of the associated correspondence CCE of HARQ feedbackCCE.The longitudinal axis, which represents, to be directed toward in PUCCH
The index n of HARQ feedback present positionPUCCH, HARQ feedback unit counts from here on.Each resource block includes several HARQ
Feedback unit.
In Figure 4 A, HARQ feedback is related to single previous downlink subframe.The HARQ feedback unit indexed from 0 to 83
It is used and related to the CCE of corresponding subframe indexed from 0 to 83.In other words, it is directed to the uplink in such a scenario
The binding factor of way frame is one.
In figure 4b, the HARQ feedback in uplink subframe is related to the unit of two previous downlink subframes.Cause
This, the binding factor is two herein.The first set 26 of HARQ feedback unit it is related to the first previous downlink subframe and
The second set 29 of HARQ feedback unit is related to the second previous downlink subframe.As can be seen that in the use of PUCCH index
In there are gaps 28.
Also it is to be noted that used maximum n between the scene shown in Fig. 4 A- Fig. 4 BPUCCHExist in index
Difference.The maximum n of the scene of Fig. 4 APUCCHIndex is 83, and the highest maximum n under the scene of Fig. 4 BPUCCHIndex is 142.
It has realized that these variations in use across the sub-frames lead to the idling-resource in some subframes, it can
To be used for other purposes other than HARQ feedback.
In different uplink subframes, due at least three, the size in activity HARQ feedback region can become
Change.
Firstly, the binding factor variations between different uplink subframes, result in the need for different number of HARQ feedback
?.As mentioned above, see, for example, two examples for bundling the factor 1 and 2, used maximum nPUCCHThe difference of index is
83 compare 142.
Secondly, PUCCH HARQ feedback index space is discontinuously possible when bundling the factor greater than 1.See, e.g.
In figure 4b, wherein nPUCCHIndex 105~109 is not used by all, produces the gap 28 in resource use.
Such case is for carrying the TDD uplink subframe for the HARQ feedback for being directed to more than one downlink subframe simultaneously
And work as HARQ feedback resource index (nPUCCH) in sequence there are when gap (either since some downlink subframes are carried than it
The more PHICH groups of its downlink subframe, or since the cyclic prefix of extension is used) can occur.This will lead to one
Less CCE is available in a little downlink subframes, this then leads to the jump as caused by fixed area in HARQ feedback sequence.
Third, when bundling the factor equal to 1, since corresponding downlink subframe is being taken between uplink subframe
The number of the PHICH group of band is different, and the size of HARQ feedback index space can be different.It is similarly to second situation, but
Here, gap is located at the end in HARQ feedback region.
The combination of a variety of causes is also possible.
The variation that this resource across the sub-frames uses is used as HARQ feedback resource and uses less than for other
Idling-resource in the subframe of subframe.
Fig. 5 A- Fig. 5 B is the net that Fig. 1 is shown using the principle of the example of Fig. 2A-Fig. 2 B, Fig. 3 and Fig. 4 A- Fig. 4 B explanation
The flow chart of resource allocation in network node.This method is performed in the network node 1 of Fig. 1 and is related to distribution as wireless
The resource of first uplink subframe of a part of electric frame.Therefore first uplink subframe is normally used as a term
It is designated as potential idling-resource and analyzed subframe and does not indicate the specific position in itself in radio frame.
Each resource is the combination of frequency range, time slot and code and associated with particular UE.In one example, each resource can be with
It is PUCCH format 1, format 1a or format 1b resource.
Firstly, by method shown in explanation figure 5A.
In the step 30 of originally determined first resource set, determines and be directed to HARQ feedback in the first uplink subframe
The first resource set distributed.
In the step 31 for determining Secondary resource set, determines and divide in the second uplink subframe for HARQ feedback
The Secondary resource set matched, second uplink subframe are a part of radio frame.Second uplink subframe is wireless
Any other subframe in electric frame other than the first subframe.
In the step 32 of identification idling-resource, by it is in identification Secondary resource set, do not have in first resource set
There is the resource of corresponding relationship, to identify idling-resource in the first uplink subframe.Therefore, because being used for across the sub-frames
Variation in the resource use of HARQ feedback, the Secondary resource set of a part by finding not formed first resource set
nPUCCHTo find any idling-resource.
As example in fig. 4 above A- Fig. 4 B, due to the change of the binding factor in different uplink subframes
Change, the identification of the idling-resource in uplink subframe may occur.Particularly, the subframe with the lower binding factor usually compares
Subframe with the higher binding factor uses less HARQ feedback resource.Bundling the factor is the parameter being easily obtained.Pass through ratio
Compared with the binding factor, a kind of simple mode is provided to identify any idling-resource.For example, see the n in Fig. 4 A and Fig. 4 BPUCCH
Difference in use.In Fig. 4 B that the binding factor is two, used maximum nPUCCHIt is 142, and is one in the binding factor
In Fig. 4 A, used maximum nPUCCHIt is 83.
The identification of idling-resource is also possible to multiple due to being used in single uplink subframe in first uplink subframe
Gap in the use of the HARQ feedback of downlink subframe and occur, such as show and solve in more detail above in figure 4b
As releasing.
In the step 33 of any idling-resource of condition criterion, this method is directed into that there are the distribution of any idling-resource
Step.Otherwise, this method terminates.
In allocation step 34, when at least one idling-resource is found, at least part of idling-resource is distributed
To the use other than HARQ feedback.In this way, idling-resource can be utilized for the output mesh in the first subframe
's.The distribution can optionally continue until that the configuration of radio frame is changed.
At least part of idling-resource can be distributed to semi-persistent resource use, such as scheduling request, use by the step
Resource in semi-durable HARQ feedback and the PUCCH format 1b resource with channel selection.Scheduling request is scarce resource.
One UE without enough resources for scheduling request is forced to use random access procedure to request UL shared channel resources.It is right
For system, random access attempts interface resource, signaling, processing load etc. in the sky and attempts expensive obtain than scheduling request
It is more.
Optionally, which can distribute to user data, such as PUSCH at least part of idling-resource.This
The idling-resource found is adjacent to previous PUSCH distribution so that at least one additional complete PRB especially has when can be used
With.
The method shown in figure 5B be the extension to method shown in Fig. 5 A and previously for Fig. 5 A it is interpreted
The step of crossing will no longer be explained, unless they are more or less different.
After the step 32 of identification idling-resource, there is the step 35 of the more other subframes of a condition criterion.In the step
Determine whether that there are also be not yet compared with the first subframe to identify the more other (except the first subframe of idling-resource in rapid
) uplink subframe.If condition criterion is that very, method returns to the step 31 for determining Secondary resource set, there
New other uplink subframes become the second new uplink subframe of the step 31 for determining Secondary resource set.
In this embodiment, if not finding idling-resource, the step of any from condition criterion idling-resource of method
33, which proceed to condition criterion, will analyze the step 37 of more subframes.
